I recently involve more in Reddit, and surprisingly find out a subreddit named AskAcademia. I know that Stack Exchange is not Reddit, and the way Reddit works is different to the way SE works. In SE, people ask and answer. In Reddit, people post a link/thinking and comment. However, in Q&A subreddit like AskAcademia, I see no different to here. Bad questions may never be closed, but they will never be raised. Can you tell me when should I ask questions on Reddit rather than Stack Exchange?
You should ask a question on Reddit whenever you feel like it, regardless of whether you ask the question on Academia.SE.
Academia.SE doesn't make any claim to be the only site you should ask a question on. It only asks that you not ask the same question on any other SE site, because that is general SE policy.
- Born for open-ended discussions
- After 6 months posts are automatically locked so discussions are "fossilized" to reflect what happened in that time
- No way for users to improve others' posts
- Downvotes can (and usually?) mean "I don't like this" or "this is uninteresting"
- The only way to have links to relevant posts within the subreddit is by having other users provide
- More active users in my opinion
- Born for Q&A
- Posts can always be improved until the Sun dies
- Contributions from users are encouraged and peer-reviewed
- Downvotes mean "This post is wrong/not useful"
- Have tag system, related questions to categorize and discover more questions/answers
- Posts can have images, HTML. The site overall is nicely designed
